Designers of satellite communication systems can help to prevent disruption to signal transmissions by using a range of redundant line amplifiers now available from Link Microtek – the specialist supplier of RF and microwave subsystems and components.
Manufactured by US company MITEQ, the robustly constructed RL-W series of amplifier systems are built for outdoor use and provide redundancy in a choice of 1:1, dual 1:1 or 1:2 configurations.
In the event of a fault condition or when initiated by an operator-generated command, the system automatically switches the standby amplifier into the satcom link while removing the original amplifier from the signal path, thereby ensuring continuous operation.
The RL-W systems can be specified with 17 different satcom bands covering frequencies from 950MHz to 33GHz. Performance figures for the standard units are a 30dB minimum gain and a +10dBm minimum power output (at 1dB compression), and these can be optionally uprated to 40dB/50dB and +15dBm/+20dBm if required.
Remote control is provided as standard via a user-selectable RS485/RS422 interface, while contact-closure, RS232 and 10/100Base-T Ethernet interfaces are also available as options.
All versions feature a wide input voltage range of 90-250VAC and use fully redundant, hot-swappable power supplies with independent AC inputs to maximise system availability.
